CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 595,888, dated DecemberV 21, 1897.

Application led September 1,1897. Serial No. 650,274. [No model.) v

To @ZZ whom it may concern:

Be it known that I, WILLIAM A. PALMER, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented a new and useful Car- Axle Box, of which the following is a specification.

The invention relates to improvements in car-axle boxes. I

The object of the present invention is to improve the construction of car-axle boxes and to provide a simple, strong, and durable device adapted to be readily applied to axleboxes and capable of forming an effective stop for the ends of the axle to prevent play of the same laterally of a car and thereby avoid injury to the axle-box, journal bearing or brass, and the axle and effecting a saving of oil and also preventing the axle-box" from becoming heated.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a vertical longitudinal sectional view of an axle-box constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a detail perspective view of the stop-bar and the bearing-sleeve. Fig. 4 is a horizontal sectional view.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

l designates a car-axle box designed for use on passenger-cars, freight-cars, tenders, and the like and provided at the inner faces of its sides with grooves 2, located beyond the end of the journal 3 of the axle and forming ways for a horizontal stop-bar 4, which is constructed of steel and which is adapted to limit and prevent all play of the axle laterally of the car. The ways 2 are substantially L- shaped and are composed of horizontal and vertical portions, the horizontal portions extending inward from the outer end o f the journal-box and the vert-ical portions depending from the inner ends of the horizontal portions and forming seats for the ends of the stop-bar.

The stop-bar, which is reversible, for a purpose hereinafter described, is rectangular in cross-section and fits snugly in the seats formed by the ways, and as the four faces of' the stop-bar are of equal width it may be turned to bring any one of its sides opposite the end of the journal. f

A rectangular sleeve 5 is arranged on the stop-bar and is provided with an opening or bore which is square in cross-section to conform to the configuration of the stop-bar, and it may be readily placed on and removed from the same when the stop-bar is taken out of the ways of the axle-box. The removable rectangular sleeve forms a bearing for the end of the journal and is designed to be constructed of brass or other suitable material, and when one of vits faces becomes worn it is adapted to be rotated a quarter-turn to bring another face opposite the axle. By this construction a bearing-sleeve may be used until all of its faces are worn, and it can then be replaced by a new sleeve.

A Each face or side of the sleeve is provided with a central circular opening 6, which serves as an oil-hole and which also is arranged so that it is located directly opposite the center punch recess or indentation 3*"L of the end of the axle when the adjacent face is opposite the lsame to prevent any liability of a bur or projection being formed at the indentation or recess through the wearing of the sleeve at the other portions of the end of the axle. lf a smooth unbroken bearing-face were presented to the end of the axle, that portion oppositey the center punch indentation or recess would be practicallyiunworn and would leave such a bur or projection which would interlock with the axle and prevent or render difficult the removal of the stop-bar and sleeve from the axle-box.

In order to lock the stop-bar in the vertical portions or seats of the grooves or ways, the cover 7 is provided at each side of the axle-box with an inwardly-extending arm 8, arranged to enter the horizontal portion of the groove or way when the cover 7 is closed and adapted to lie directly above the stop-bar, as clearly shown in Fig. l of the accompanying drawings. These arms 8 positively retain the stop-bar in the vertical portions of the ways and prevent the same frornAbecoming accidentally displaced.

IOO

A journal brass or bearing l0 is arranged upon the journal of the axle in the ordinary manner, and it is protected by the stop-bar from those injuries resulting from longitudinal movement of the journal in the axle-box and the durability of the journal bearing or brassis thereby increased.

The invention has the following advantages: The stop-bar prevents play of the axle laterally of a car and thereby avoids the cutting of the journal bearings or brasses,

and at the Sametime it prevents injury tov the journal-box and j ournal.' It also prevents the undue heating of the box and journal resulting from a breakage of the journal-brass, and it in this manner effects a saving of the lubricant. It renders cars and tenders more steady by eliminating the lateral swinging motion. The holes in the bearing-sleeve perform a double function in serving as oil-holes and in preventing the center punch depression of the axle from raising a bur and locking the stop-bar in the ways.

The stop-bar may be readily rotated successive quarter-turns to bring the four faces of the sleeve successively opposite the end of the axle, and When the sleeve has become thoroughly Worn it may be readily replaced by a new one.

Changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrifieing any of the advantages of this invention.

What I claim is- 1. In a device of the class described, the combination with an axle-box, and a journal,

v of a removable and reversible stop-bar interlocked with the axle-box and extending across the end of the journal, and abearing-sleeve detachably arranged on the stop -bar and adapted to be rotated to bring its faces successively opposite the end of the journal, substantially as described.

2. In a device of the class described, the combination With an axle-box, and a journal having a central indentation in its end, of a stop-bar extending across the end of the journal and carrying a bearing-face disposed opposite the axle, said bearing-face being provided with a central opening registering with the central indentation of the journal,where by the formation of a bur or projection on the bearing-face is prevented and an oil-hole provided, substantially as described.

3.` In a device of the class described, the combination with an axle-box, and a journal, of a stop-bar extending across the end of the journal and interlocked with the sides of the axle-box, said stop-bar being removable and reversible, a polygonal-sleeve removably arranged on the stop-bar and adapted to be partially rotated to bring its various faces successively opposite the journal, said sleeve being provided with holes arranged centrally of its faces, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

WILLIAM A. PALMER.
